suppose there are 5 checkboxes and a submit button which goes in servlet.now how to known which checkboxes are checked and which are not from the servlet
Only the values from the checkboxes which are checked will be sent to the servlet. Retrieve the values using getParameterValues(String). For example, given this snippet of HTML <form> <input type=checkbox name=Test value=1>One <input type=checkbox name=Test value=2>Two <input type=checkbox name=Test value=3>Three </form> If the user checked the boxes labelled One and Three, then this code in your servlet String[] values = req.getParameterValues("Test"); will result in values being a 2 element String array such that one element will be "1" and the other element will be "3".
